The Acalanes Dons freshman team wasted no time asserting themselves in their season finale against Mount Diablo, capping a season for the ages. 

They controlled the first 10 minutes with relentless pressure and crisp ball movement and it paid off early.

Winger Mason Foster (#11) made a strong run down the left flank and delivered a perfectly weighted cross along the ground to Calder Williamson (#13) on the right wing, who slotted it home neatly for the first goal of the match.

Just two minutes later, chaos in the box led to the second. A ball ricocheted off David Penn (#17) and a defender before landing at the feet of Jonny Rubin (#9). With the goalkeeper out of position, the attacking midfielder calmly finished to make it 2–0.

Mount Diablo responded with a long free kick from about 40 yards out that drew the goalie out of position, allowing their striker to place the ball into the back of the net, cutting the lead to 2–1.

Acalanes, sensing the urgency to squash any momentum from Mount Diablo, answered before halftime. A beautiful switch from Williamson across the field found Keegan Aldridge (#7) streaking down the left side. Aldridge buried it far post to make it 3–1 heading into the break.

The second half began with immediate fireworks. One minute in, a perfectly threaded pass split the defense, and Mason Foster (#11) finished clinically with his right foot into the left side of the net making it 4–1.

Then came a moment of individual clarity. Nicholas Siewert (#15) took on two defenders starting near the 40, threaded through traffic with persistence, and finished strong to notch the last goal of the game. 

Calder Williamson was named Man of the Match for his goal, assist, work rate, and impact in the final game of the year.

The last line of defense

No team can go undefeated without a phenomenal backline and keeper. Luckily for the 2026 Acalanes Freshman team, they had a stalwart group of young men who thwarted mounting pressure like they were taking candy from a baby. 

 

Matt Roberts and Lucas Leingang shared goalkeeping duty all season, allowing a combined 5 goals in 15 games and amassing 10 clean sheets. 

 

The powerful defense was anchored by Logan Lewis, Owen Lee, and Luke Fratarcangelli. Unsung hero, Kacper Zarzycki, manned the holding midfield position with a grace and calm that set the tone for every game.

 

The Bigger Picture

Undefeated seasons are rare. Undefeated seasons with this level of offensive production are even rarer.

The 2026 Freshman Dons combined:

• Aggressive, relentless dominance

• Clinical finishing

• Selfless ball movement

• Depth across the roster

• Consistent league control

From top scorers to defensive stalwarts, 15 different players registered points this season. That is what team soccer looks like.

The Dons did not rely on one or two players to carry the load. They attacked in waves, created chances through unselfish play, and trusted whoever stepped into the moment.

A season defined by dominance.
